6 Claims. (Cl. 298-7) dangerous to vehicles running off of the paved surface.

It is difficult to maintain a smooth continuous shoulder surface adjacent the paved strip and to keep this rut filled with suitable aggregate material.

It is an object of this invention to provide an attachment for conventional dump trucks specifically for the purpose of filling such ruts in the road shoulders adjacent the edge surface of the highway strip.

It is another object to provide an easily attached discharge spoutadapted to receive and guide a steady stream of aggregate filler material down onto the road surface adjacent the highway strip thereof and to controllably vary the elevation of the top surface of the filler aggregate relative to the adjacent marginal edge portion of the hard surface highway strip to ultimately permit a smooth and substantially continuous surface to be obtained between the shoulder and said hard surface pavement.

More specifically, it is an object to provide a pivotally mounted, easily retractible and easily detachable discharge spout of the class described for discharging a controllable Fig. 1 is a longitudinal sectional view' partially in side elevation showing my discharge spout in attached position on the rear of a conventional dump truck;

Fig. 2 is a top plan view thereof showing the beveled guiding partitions in the rear of the dump body of the Patented Sept. 25, 1956 ice the sides of discharge opening 8a, as best shown in Figs. 1

the upper edge portions of said panels 10 and transversely corresponding notches of said panels form a pair of cradles in which a chute mounting rod, to be hereinafter described, is pivotally received. An anchoring aperture is provided through an intermediate portion of each of the side panels 10 and said cradle forming notches 10a of each of said panels are arranged along the arcuate circumference of a circle with said anchoring aperture taken as a center for purposes that will hereinafter be set forth.

A discharge spout having a cylindrical portion 12 is provided and has a curved elbow portion 12a at the lower end thereof to form a generally circular discharge mouth lying in a substantially horizontally disposed plane. A receiving and guiding hopper 13 is formed at the upper end of the discharge conduit 12 and the forward end of said hopper 13 has a generally rectangular shaped box 13a which surrounds the discharge mouth opening 8a. and is of a size to receive the mounting panels 10 and apron 11 therewithin. The box portion 13a has a pair of upstand ing side panels which overlap the upstanding panels 10, as best shown in Figs. 1, 2 and 3, and are disposed in slightly spaced relation outwardly therefrom. A straight bottom panel or plate 13b extends rearwardly from the upper end of cylindrical spout portion 12 to the rear ends of the panels 13 and underlies the apron 11, as best shown in Fig. 1.

The hopper 13 is pivotally anchored to the tail gate 8 on the trunnion forming mounting rod 14 which extends between th side panels of box 13a, as best shown in Figs. 1, '2 and 5. Said trunnion rod 14 is selectively received in a pair of transversely opposed cradle notches 10a. The weight of the rearwardly extending: hopper 13 and cylindrical spout portion 12 maintains the forward edge of theunderlying hopper plate 13b in abutting relationwith the lower portion of the tail gate 8 when the dump body is in normal lowered position but the piv- Fig. 1.

Oral mounting of said hopper 13 on the mounting panels 10 permits the same'to swing upwardly when the lower end thereof is in ground supported discharge position Withdump bodyin dumping position as best shown in Suitable means for positively anchoring the trunnion rod 14 in the selected pair of cradles are provided, such as the pair of anchoring hooks 15, each having a laterally outwardly extending attachment pin 15a adapted to be mounted through the anchoring aperture through the intermediate portion of each of the upstanding mounting panels 10, as best shown in Figs. 1 and 4. Obviously, the distance from attachment pin 15a to the closed .end of hook 15 is always the same,

I therefore requiring that the distance from said aperture to the trunnion rod 14 always be the same. ,Therefore,

A conventional dump truck body 7 is illustrated in the accompanying drawings and has a tail gate 8 with a center discharge opening formed therein. A pair of beveled partitions 9 are fixed across the rear corners of thedump body 7 to guide the aggregate into the opening 8a in the tail gate 8.

A pair of upstanding side panels 10 are securely fixed in rearwardly extending relation to the tail gate 8 adjacent by positioning said notches 10a along a circular are described with said anchoring aperture as a center, permits i said trunnion rod to be maintained at the same distance frorn the anchoring aperture regardless of the selected trunnion "cradles in which the rod 14 is mounted.
